Higher Order Mode

An analysis of higher-order mode effects in a parallel-plate wave guide is presented. Green's functions for the wave guide are derived in the frequency domain which can be inverted analytically to give the step function response for the TM modes and the delta function response for the TE modes. Plots of the responses are given for different excitation functions and the results are interpreted physically at various locations in the structure.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.
